Dynamic text (with HTML) and an embedded font

Hello all.
Here’s my situation.
I’ve been scouring the internet for years trying to answer this problem, but now I’m pressed for an answer… I’m working on a project in which the design team has sold the client on this non-standard font.

I’m looping through an XML file and populating an array.
I’m calling a function to fill dynamic text boxes with the appropriate array element.
I’m embedding the font.

Everything works fine, but once I “Render text as HTML” the text doesn’t show up.
Has this been resolved? Is there a workaround?
(I’ve also tried creating a “New Font” and the same problem exists… once I check the checkbox to make HTML available, the text doesn’t show up.)

Many thanks to anyone who can answer this.
